The unregistered version of Anti-keylogger™ anti-spyware software is fully functional for 4 (four) hours from the moment of the system restart, after that the program switches off. The program re-launch will be possible only after the operating system is reloaded. The number of system reloads is restricted to 10 (ten). When the limit is reached, the program will cease to work and it should be either uninstalled or registered.
